How to replace existing Mozc in my Ubuntu with a new new one from sources?

[username30]

Hello and first of all, thank you for your great project!

For quite long time I'm struggling with this issue https://bugs.launchpad.net/ubuntu/+source/mozc/+bug/1931554 myself. From what I see, it was already fixed few months ago in official git source codes. But unfortunately latest version of Mozc available for Ubuntu 21.04 - that I'm using - in it's repositories is 2.26.4220.102 with a version that contain the fix is 2.26.4472.100, so straight

sudo apt update && sudo apt upgrade

does not help.

I was trying to dig into your official docs for building Mozc in Docker environment https://github.com/google/mozc/blob/master/docs/build_mozc_in_docker.md , but unfortunately my knowledge of Ubuntu is lacking to replace present Mozc system with the new one, and I can't find proper guidelines for it in official docs, neither anywhere in answers on askubuntu for example - with later mostly address Mozc installation for older versions of Ubuntu from official apt repository.

Regarding building instructions, after this command

sudo docker build --rm -t $USER/mozc_ubuntu20.04 .

I get this output

and then after

sudo docker run --interactive --tty --rm $USER/mozc_ubuntu20.04

I just get some new prompt

I figured out I need to put

bazel build package --config oss_linux -c opt

there, but then I just get

again... and with my terribliest apologies, this is where I'm stuck. I mean, I see everything went great so far and now I just have to do something trivial to complete update and just replace something somewhere... But I'm just out of clue what and where.

I've tried to ask this question on askubuntu, but nobody know what to do there as well.

I would appreciate a lot if anybody could give a bit more detailed steps for building and replacement this system from github sources, without waiting for official Ubuntu repository to be updated.

Hi,

#510 is the corresponding issue to https://bugs.launchpad.net/ubuntu/+source/mozc/+bug/1931554.

So, you might want to update /usr/lib/ibus-mozc/ibus-engine-mozc with your build.

Please try to copy bazel-bin/unix/ibus/ibus_mozc to /usr/lib/ibus-mozc/ibus-engine-mozc.

The steps are something like:

• sudo mv /usr/lib/ibus-mozc/ibus-engine-mozc /usr/lib/ibus-mozc/ibus-engine-mozc_orig
• cp -f bazel-bin/unix/ibus/ibus_mozc /tmp
• sudo cp /tmp/ibus_mozc /usr/lib/ibus-mozc/ibus-engine-mozc
• sudo chmod 755 /usr/lib/ibus-mozc/ibus-engine-mozc

I also added the information about build paths and install paths to the document.
